This invention relates to wireless telecommunications systems, specifically methods for dynamically managing radio resource allocation during higher layer data transmission. The problem addressed is inefficient use of allocated radio resources when a transmitter entity needs to transmit additional data during an ongoing higher layer data transmission period. The solution involves a transmitter entity first allocating radio resources for higher layer data transmission and notifying the receiver entity. During transmission, if unused allocated resources are needed for other data, the transmitter identifies a subset of these resources, restricted to predefined sizes and locations, for the additional transmission. The transmitter then conveys this subset information to the receiver. This dynamic reallocation ensures efficient resource utilization while maintaining structured communication. The predefined constraints on subset sizes and locations help avoid conflicts and ensure compatibility with system protocols. The method optimizes resource allocation without disrupting ongoing transmissions, improving overall system efficiency.
2. The method of claim 1 , wherein the method further comprises dividing the higher layer data into a plurality of higher layer data code blocks and applying error detection coding to individual higher layer data code blocks before transmission to the receiver entity, whereby detection of an error by the receiver entity during decoding in respect of one or more of the higher layer data code blocks provides the receiver entity with the indication of the subset of allocated radio resources used for the transmission of other data.
This invention relates to wireless communication systems, specifically improving error detection and resource allocation in data transmission. The problem addressed is the need for efficient error detection in higher layer data transmissions, particularly when using allocated radio resources, to allow a receiver to identify which resources were used for other data transmissions. The method involves dividing higher layer data into multiple code blocks before transmission. Each code block undergoes error detection coding, such as cyclic redundancy check (CRC), to enable the receiver to detect errors during decoding. If an error is detected in one or more code blocks, the receiver uses this as an indication of which subset of allocated radio resources was used for transmitting other data. This allows the receiver to distinguish between higher layer data and other data transmissions, improving resource utilization and reducing misinterpretation of transmitted data. The method ensures that error detection is applied at the code block level, providing granular error feedback.
